Broker Willis is to supply its UK employees with masks to filter out dust and debris to protect them from a possible terrorist attack.
Willis spokesman Nick Jones told Bloomberg that "[Willis is] conducting itself in a very professional and sensible manner."
He confirmed that a memo has been sent to staff advising they will all be given "a dust mask to use in the event of an emergency such as a bomb blast."
Meanwhile Bloomberg also reported that security measures have been stepped up at Lloyd's.
